A smooth, oblique-angled endface fracture of an optical fiber 39 useful in low reflectance, low insertion loss mechanical splices is achieved by creating tensile stress in the fiber and scoring the fiber at an angle to its longitudinal axis. Tension may be applied by bending the fiber with a flexible platen 16 to which it is affixed, and the scoring may be accomplished by scribing the fiber surface with a sharp point or impressing a notch into the fiber with a blade 28.

A smooth, oblique-angled endface fracture of an optical fiber 20 useful in low reflectance, low insertion loss mechanical splices is achieved by tensioning the fiber while it is in contact with the abrupt edge 23 of an anvil 22 and applying a shearing force to the fiber at a point closely offset from the anvil edge and in a direction substantially perpendicular to the longitudinal axis of the fiber.
